Steering wheel shimmy often occurs when the vehicle is driving, which affects both riding comfort and driving safety. This article is to find out the reasons through the tests on wheel positioning, wheel dynamic balance, steering gear, and wheelbase parameter adjustment from the perspective of experimental verification. The results show that the dynamic balance that controls the tire assembly is between 0 and 5g. Actions like accurate calibration on the front wheel positioning parameters, adjustment on the free travel of steering gear and steering system, and wheelbase deviation to be controlled within 10mm, can eliminate the steering wheel shimmy.
